ABSTRACT:
Apparatus and method for crimping fiber, especially polypropylene fiber, includes feeding a tow through driven rolls into a stuffer box. Heat, in the form of steam, is applied to the tow prior to the rolls. The stuffer box includes doctor blades for cooling the tow. The doctor blades include a leading tip portion, through which compressed air is fed over the tow, and a trailing section including at least one internal compartment for a cooling fluid.
